[JBoss-user] [JBoss jBPM] - Re: HibernateException when calling ProcessInstance.getTaskM
Ok, we solved it! The problem dissappeared by doing 2 changes to our code: 1. Persisting the process definition before saving the process instance 2. Putting calls to beginTransaction() and commitTransaction() around the saving of the process instance (and around the saving of the process definition) We didn't do 1 before because we'll have just one process definition, no more than one version of it, and we didn't see the part of docs where it says that we must persist process definition before its instances. We didn't do 2 because we were planning to put some transaction interceptor around those methods (which weren't in place yet). So, is this the expected way of this stuff to work?

The database example in Chapter 3 of the jBPM user guide starts with saving the definition... plalloni wrote : we were planning to put some transaction interceptor around those methods (which weren't in place yet) Hibernate (and hence jBPM) can be made aware of managed transactions, in which case the calls to beginTransaction() or commitTransaction() need not be present. You must explicitly demarcate transactions in an unmanaged environment. If you want to move freely between both environments, just leave the demarcations. Hibernate will ignore them in the managed case.

I wonder if you solved this issue and how you did it since we're having the very same problem right now and we're completely lost... Have you?

Unfortunately I haven't, because we've abandoned the whole jBPM and Implemented our own workflow solution. Because it seems that the jBPM is still immature and bug infested.

Well... we really don't want to switch BPM engines ATM so here is my stack trace.

[JBoss-user] [JBoss jBPM] - Re: HibernateException when calling ProcessInstance.getTaskM
I ran into a similar problem when using the Hypersonic database within jBoss
and my temporary solution when saving a ProcessDefinition was to catch the
exception that is generated during the commit.
As in:
jbpmSession.beginTransaction
jbpmSession.getGraphSession().saveProcessDefinition( pd )
try
{
jbpmSession.commitTransaction();
}
catch( Exception e )
{
// Ignore
}
finally
{
jbpmSession.close();
}
I found that things gets persisted correctly even though the exception is
generated. I don't like ignoring the exception but I don't know enough about
Hibernate and its configurations and I don't have a sufficient development
environment to investigate further.
